Description
RealStamp Verify turns any WordPress post into a cryptographically verifiable piece of human-authored content. Patent pending. Each stamp is:
- Signed by a verified human (WebAuthn + liveness)
- Cryptographically bound to the exact content (SHA-256)
- Anchored in the public Sigstore Rekor transparency log (Linux Foundation)
- Verifiable independently with no trust in any single party
- Compatible with the C2PA Content Credentials standard (Adobe, Microsoft, BBC, NYT)
Three ways to add a badge:
- Gutenberg block — drop the RealStamp Verify block anywhere and paste a pulse token.
- Shortcode —
[realstamp token="xK9mP2..."] - Auto-detect — set a post custom field
realstamp_pulse_tokenand the plugin injects a badge automatically.
Who is this for?
- News publishers fighting AI slop
- Creators proving original work
- Legal and forensic publishing
- Any site that wants to display a content-provenance trust signal
How it works
You create a stamp at realstamp.app on your original content. You get a portable pulse token (JWT / SD-JWT). You paste that token into your WordPress post. Readers see a badge; clicking it opens the public verification page which proves: (a) the signer was a real verified human, (b) the content has not been altered since stamping, (c) the stamp is anchored in the public Sigstore Rekor log.
Requires a RealStamp account
This plugin is a consumer of the RealStamp service. Get started at realstamp.app.
Privacy
This plugin embeds a script from cdn.jsdelivr.net which loads the RealStamp Verifier SDK web component. No user personal data is sent to third parties by the plugin itself. When a reader clicks a badge, their browser may contact realstamp.app to verify the stamp.

FAQ
-
Do I need an API key?
-
No. Verification is public — anyone can check any stamp. You only need a RealStamp account to create stamps.
-
Does this slow down my site?
-
Minimal impact. The Verifier SDK is a ~10 KB ES module loaded from a CDN with deferred execution. No server calls are made until the badge is clicked or a user scrolls it into view.
-
Is my content data sent anywhere?
-
No. Verification checks only the signed pulse token. Your post content is not transmitted during verification.
-
Does this work with AMP?
-
The current build uses a web component that is not AMP-safe. An AMP-compatible version is planned for 0.2.
-
Can I verify stamps offline?
-
Yes — with the offline mode of the SDK. Not exposed in this plugin UI yet; will land in 0.2.
